This is a quick guide where you can flash the backup that you had made using MTK Droid Tools on my previous post. If you have not created a backup yet then click on this LINK and create one. Creating a stock rom backup is essential if you find your device not booting, getting stuck on splash screen/bootanimation or if you just want to revert back to your stock rom.
VCOM Drivers : MTK65xx Preloader Drivers
SP Flash Tool : v3.1304
Backup created by MTK Droid Tools or Gscript
NOTE: Make sure that you are flashing the correct rom for your device if not you may end up with a nice paper weight. Also make it a habit to not flash the PRELOADER and the DSP_BL file even if the backup came from your own device. The site nor the author will not responsible if you brick or damage your device/computer by doing the steps below.
First install the vcom drivers on your computer provided on the link above. Now once the installation is complete extract the SP Flash tool to your desktop or any location where you can easily access it. Open "Flash_tool.exe". (Check image below for reference)
Click on "Scatter-loading" on the right side and locate the scatter text file. There are other software which can create scatter text file but in this case we will be using the one that was created automatically by the MTK Droid tool. Once the scatter text has been loaded you will see a similar image below. (If you are getting an error message when loading the scatter text delete the preloaded file from your backup)
Now if you don't want to flash all the images like you only want to flash boot.img or recovery.img then remove the check mark on the other images. In the picture below I will only be flashing the recovery.img.
Click on "Download" button on the top and if you have deleted the "preloader" file or have not selected all images. A message would tell you that "Not all images are loaded. Do you want to continue?" We can just click on "YES" if you want to select more images to flash click "No".
Turn off your phone and remove the battery. Then once the battery has been removed connect the phone to your computer then reinsert the battery.
Turn off your mobile phone and remove the battery for a few seconds. Reinsert the battery then connect the phone to the computer.
Once you have connected the mobile phone to the computer we should get a response from the SP Flash tool with a red bar on the bottom. If not try re-doing option A or B until you see a response from the program. (See image below)
